- The ratio of the heights of the pyramid given at the end of the answer is of: 1:3.
- The ratio of the surface areas of the pyramid given at the end of the answer is of: 1:9.
- The ratio of the volumes of the pyramid given at the end of the answer is of: 1:27.
The first step in obtaining the ratios is finding the ratio of the heights, which is given as follows:
5:15 = 1:3.
The heights are measured in units, while the surface area is measured in units squared, hence the ratio is squared, as follows:
(1:3)² = 1:9.
The volume is measured in cubic units, hence the ratio is cubed, as follows:
(1:3)³ = 1:27.
<h3>Missing Information</h3>The pyramid is given at the end of the answer.
For different dimensions, the procedure of taking the ratio of the heights, then the surface area is squared and the volume is cubed remains.

Answer:
The population mean is 5 volts
Step-by-step explanation:
Output voltage is assumed to be normally distributed, with standard deviation 0.25 Volts
s=0.25
n = 8
Sample mean =
Since n < 30 and population standard deviation is unknown
So, we will use t test
Formula :
t=-1.69
Refer the t table for p value
Degree of freedom = n-1 = 8-1 = 7
So,
P value >α
So, We are failed to reject null hypothesis
Hence The population mean is 5 volts
